Preheat oven to 200 C / 392 F.
Line a large baking sheet with parchment paper.
Chop strawberries.
Mix dry ingredients: flours, sugar, baking powder, salt.
Combine wet ingredients to dry and fold in chopped strawberries.
Pour cake batter on the baking sheet and spread until it's a large cake almost the size of the sheet (about 3/4 the size).
Bake for 20-25 minutes or until toothpick test comes out clean. If the cake is very thin and large check the cake earlier, already after 10-15 minutes.
Let cake cool.
Blend strawberries until you have a strawberry puree.
Mix whipped cream, sugar and strawberry puree to make strawberry cream.
Spread cream on top of cake and decorate with more strawberries. Enjoy!
